Quick update on this: We have deployed a fix that means new Mastery Pass purchases will work properly, players that purchased between 10/15 and that fix are, unfortunately, still unable to properly earn Mastery Pass rewards. We are continuing to work to solve that problem, and we will ensure that all players get all of the Mastery Pass rewards they have earned.
